The backend-agnostic trusted_key_options structure carries TPM-specific fields. With the recent addition of a backend-private pointer, these fields can be moved out of the generic options structure.
This patch series intends to reloacte all TPM-spcific fields into a newly defined trusted_tpm_options structure. A pointer to the trusted_tpm_options struct is stored in trusted_key_option's private. Along with the migration of TPM-specific fields, this patch series includes a preparatory clean-up patch: replacing pr_info() with pr_debug() and using KERN_DEBUG for print_hex_dump() for logging debug information. Testing covered both TPM 1.2 and TPM 2.0 backends (virtual environment), including trusted key creation, revocation, unlinking, invalidation, and loading keys from encrypted blobs. I would welcome any additional testing from upstream to further strengthen the validation. Changelog: v2: * Exclude the bug-fix patch as it has already been applied to 6.19-rc7 * Rename instances of trusted_tpm_options from tpm_opts to private * Use pr_debug and KERN_DEBUG for logging debug messages (preparatory clean up patch) * Address comments from Jarkko Srish Srinivasan (2): keys/trusted_keys: clean up debug message logging in the tpm backend keys/trusted_keys: move TPM-specific fields into trusted_tpm_options include/keys/trusted-type.h | 11 -- include/keys/trusted_tpm.h | 14 +++ security/keys/trusted-keys/trusted_tpm1.c | 129 ++++++++++++---------- security/keys/trusted-keys/trusted_tpm2.c | 51 +++++---- 4 files changed, 111 insertions(+), 94 deletions(-) -- 2.43.0
